A push button refers to a small physical mechanism that is typically built into an electrical or electronic device. It is designed to be pressed or pushed by human fingers or other objects to activate a certain function or operation. The term "push button" is derived from the action of applying force to a button, causing it to move inward and then return to its original position when released.
In electronic devices, a push button is often used as a user interface component to interact with the device or initiate a specific action. It can be found in various forms, such as a standalone button, a membrane button, or integrated within a keypad. When pressed, the push button completes an electrical circuit, allowing current to flow and triggering a predefined response, such as turning a device on or off, changing settings, or executing a command.
Push buttons are widely used in different applications and environments, from household appliances and consumer electronics to industrial machinery and control systems. They provide a simple and intuitive way for users to engage with a device or initiate a desired operation. The design and placement of push buttons may vary, ranging from a single button to a complex array of buttons with different shapes, sizes, colors, and labels to enhance usability and functionality.
The word "push button" can be broken down into two parts: "push" and "button".
"Push" comes from the Middle English word "puschen" meaning "to thrust, push". It can be traced back to the Old French word "poulser" and the Latin word "pulsare" meaning "to push or beat".
"Button" comes from the Old French word "boton" meaning "bud, button". It is thought to have originated from the Latin word "bottōnem" which means "a bud, shoot, or knob".
So, in combination, "push button" essentially refers to a button that can be pushed or pressed to activate a particular function or mechanism.
